Who’s to blame for these Halloween shenanigans?

So the mob of Halloween pranksters who have in the past caused trouble with eggs and shaving cream on Clare Castle Drive moved their headquarters Halloween night to a new street — Danielwood Drive.

About 200-300 teenagers threw eggs, shaving cream and silly string mostly at one another, police said, and were done by about 9:30 p.m. Police made no arrests.

Here’s the interesting part: The kids’ parents dropped them off (away from their own neighborhoods, obviously) and picked them up later. They weren’t wearing costumes and had backpacks full of eggs and shaving cream.

The only way I would have allowed my teenagers out into the night last night was if they were wearing well-thought-out costumes and carrying nothing but a trick-or-treat bag and possibly a princess wand.

What do you think of this? Should the police have done more? Do these parents need egg in the face?
